VVFL got lighter but is now darker? What is my body doing?

Jenny

Okay. So I tested at 9DPO and got VVFL. As the days progressed they got lighter then disappeared. This morning at 14 DPO the line was back and darker.

Can anyone explain this? I was sure the disappearing line meant I was due for another MC. Now I don't know what to think.

All tests with FMU.

I'm sure I'm pregnant, I'm just not sure if I should be worried that is won't stick?

Thanks and baby dust!
